Abstract

The role of electrode potential in CaCO₃ scaling behavior and kinetics on carbon steel and stainless steel surfaces is investigated through electrochemical tests, surface characterization, and numerical modeling. Under cathodic conditions, calcite is the dominant CaCO₃ polymorph, its lateral growth on steel surfaces follows exponential kinetics. However, under gradually promoted corrosion conditions of carbon steel, the presence of corrosion products induces more aragonite deposition and inhibits the lateral growth of CaCO₃ scale, gradually evolving from exponential to linear kinetics. This work provides further insight into how the cathodic and anodic reactions of steel corrosion respectively promote and inhibit CaCO₃ scaling.

阴极和腐蚀条件下电极电位在钢表面 CaCO3 结垢中的作用

通过电化学测试、表面特征描述和数值建模，研究了电极电位在碳钢和不锈钢表面 CaCO3 缩放行为和动力学中的作用。在阴极条件下，方解石是主要的 CaCO3 多晶体，其在钢表面的横向生长遵循指数动力学。然而，在碳钢的逐渐促进腐蚀条件下，腐蚀产物的存在会诱导更多的文石沉积，抑制 CaCO3 鳞片的横向生长，并逐渐从指数动力学演变为线性动力学。这项研究进一步揭示了钢腐蚀的阴极反应和阳极反应是如何分别促进和抑制 CaCO3 结垢的。
